I'm afraid this kind of thing probably happens at a lot of places. Where I used to work quite a few of the women (myself included) believed that the woman who cleaned the restrooms was using the same rag for pretty much everything in the restroom including wiping the toilet seats. I don't think any of us actually stood around long enough to actually prove that was what she was doing but I would wash my hands and then not touch anything else and after getting back to my desk I would use anti-bacterial gel. It was disgusting. I'm not saying it's okay that it happened at Disney (it's not) but I don't think it is a training issue so much as it is the attitude of the worker just not caring. I think it is common sense to not clean a table with the same mop you cleaned the floor with or don't use the same rag you used to wipe the toilets on the sinks.
